A company is establishing a dedicated 1 Gbps AWS Direct Connect connection between its on-premises infrastructure and its AWS account VPC. The architecture involves a transit gateway and a Direct Connect gateway to interconnect multiple VPCs and the on-premises network. To facilitate connectivity to VPC resources via a transit VIF using the Direct Connect connection, which two steps should be taken?
Explanation:
To meet the requirements of connecting to VPC resources over a transit VIF using the Direct Connect connection, the following steps are necessary:
Enable the advertisement of on-premises network prefixes over the transit VIF (Option B). This allows the VPCs to route traffic to the on-premises infrastructure.
Enable the advertisement of VPC prefixes from the Direct Connect gateway to the on-premises network over the transit VIF (Option C). This ensures that the on-premises infrastructure can route traffic to the VPC resources.
Options A, D, and E are not required for achieving the stated goal. Upgrading the connection to 10 Gbps (Option A) is unnecessary unless higher bandwidth is needed, which was not specified in the question. Options D and E are related to MACsec encryption, which is not relevant in achieving the connectivity described in this scenario.
